Transcripts

today we are going to discuss about the

fascinating World beneath our feet that

is soil and mineral resources like Fel

spass quarts micas olivines and amphib

bolts Fastpass are the group of alumino

silicate minerals that contain calcium

sodium or potassium quartz is a very

good combination of oxygen and silicon

micas that contain aluminium potassium

magnesium Etc then olivin are magnesium

ion silicate and amphiboles are

inosilicate minerals as the introductory

part of course we can start with the

soil and different types of minerals

there so soil and minerals might not be

the first thing that comes to mind when

we think about trash but they are

actually vital for our existence and

prosperity why we are concerned about

soil and soil minerals what are the

importance of soil and soil minerals how

are they treating us in various ways all

these questions can be answered in our

session so we can start with the first

question that is what is soil so it is

an interesting question it's very common

so many stories and informations are

available about it right soil is not

just dust it's a complex mixture of

minerals if people just see around your

world or around your feet then

immediately you can find the same thing

so it contains organic matter water air

and normal components of soil and it is

the foundation of life on Earth am I

right or not they are supporting plants

animals even humans and so so to some

extent we can refer an interesting

factor that is actually the origin of

humans Earth so that much importance can

be given to the soil again if we are

discussing the importance of soil the

soil cannot be

overstated it's the medium in which

plants grow providing them with

nutrients water and support so all these

contents are actually there in the soil

so they are the reservoir for all these

kinds of materials healthy soil they

also play a crucial role in regulating

water flow then filtering pollutants and

storing carbon however you know that

they are very interesting factors what

are the different kinds of functions

normally performed by the oil how do you

think that it is a comprising here so it

is under threat under threat you know

that is under threat it is everything

that we are saying that human population

or as any kind of animal population

plant population everywhere that we are

using the word threat threat here it is

the soil is also under threat from

various factors like erosion very common

there in nowadays pollution and over

usage if we don't take care of our soil

we risk losing its fertility and ability

to sustain life yeah it's all about soil

and then let's turn our attention to

Mineral Resources so that is our topic

let's discuss about mineral resources so

minerals they are building blocks of our

modern society used in everything from

constructions to electronics so normally

we are categorizing the minerals there

are two main types of mineral resources

the first one is metallic second one is

non- metallic normally we are discussing

about the factors abiotic and biotic

factors in the ecosystem so we are just

considering the same kind of idea here

also but not exactly and we are talking

about importance of the mineral Souls

here metallic minerals include gold

silver iron Etc actually there are so

many types of metallic minerals while

non- metallic minerals that include

Limestone gypsum salt and so on so it is

actually various chemical elements that

is the major problem here you know if

soil doesn't contain these kinds of

minerals or it contain something that we

are not going to be used then there is

no demand for soil unfortunately it is

comprised with these kinds of contents

and the problem is it's offer usage

everywhere everywhere that is happening

and it is actually very strong

economically these elements are very

strong giving more economic power to the

particular region or the nation so what

are the importance of mineral resources

mineral resources Es are essential for

economic development and technological

advancement we cannot refuse that they

are used in infrastructure projects

manufacturing processes energy

production so many so many applications

are there for these minerals so these

are not simple mechanisms either

infrastructure projects manufacturing

process energy production these are the

indicators of economy of the country may

be controlled by the mineral resources

so many examples are they since we are

clear about the potentiality of soil and

minerals we have the facility to extract

purify and use the soil and minerals but

there are certain kinds of serious

problems associated with it so-called

challenges challenges right however

mining for these resources can have

negative environmental impacts such as

habitat destruction air and water

pollution and greenhouse gas emissions

so everything is happening as a result

of this so-called

development we all are very wored with

these words environmental pollution

isn't it day by day we are hearing we

are discussing and we are writing about

environmental pollution everywhere then

again that we are are using another word

Environmental Protection Environmental

Protection but so far we did not realize

the real phase of environmental

pollution just imagine if you're working

kilometers for drinking water suffering

with polluted air fog appearance like

our Capital City these are just a step

door distance approaching us and it will

reach in our place very soon yes this is

reality where will we go then how can we

hide or escape from these crucial

effects of environmental pollution to

mitigate these impacts it's crucial to

adopt sustainable mining practices such

as reducing waste reclaiming land and

using renewable energy resources these

are several suggestions were made to

minimize the impact but practically it

is difficult to follow you know why

money we are utilizing all these

minerals for money we lost our thinking

capacity to take a wise decision to

whole system the policy makers the

supporters everyone but the real fact is

is we know we are in danger and waiting

for someone to help us so I concluding

here with the statement of soil and

mineral

resources they are invaluable assets

that sustain life and drive progress

it's our responsibility to protect and

manage these resources wisely for the

benefit of current and future

Generations thank you for listening

let's work together to ensure Ure a

sustainable future for our planet thank

you
